Storage, allowing energy to be conserved for periods of low production, is a second growth market. Home storage is about to become widespread. For a long time, lithium-ion batteries were considered too expensive for domestic usage, but in recent years their price has fallen from EUR 400 per kWh of storage capacity to EUR 107 per kWh. The market research company EupD Research predicts that there will be 8 million such storage units in private households worldwide by 2030. With around 125,000 installed home storage units, Germany is already the largest sales market.
A third market with bright future prospects is charging station infrastructure for electric cars. By the end of 2018, there were 150,000 e-cars in use on German roads, and as of mid-2019 there were more than 20,000 public charging stations for them – a yearly increase of 50 percent. The number of charging stations will continue to rise thanks to a government subsidy programme to support the infrastructure. The target is to get at least ten million electric vehicles on German roads by 2030. Companies that offer charging column hardware or billing systems will also find a wealth of opportunity in Germany.
